Answer:

f(x) = g(x - 3)(x - 5) for some g

f(x) = g(x^2 - 8x + 15)

Substitute (4, -1) for (x, f(x)) and solve for g.

-4 = g(4^2 - 8(4) + 15)

-4 = g(-1)

g = 4

f(x) = 4x^2 - 32x + 60

Express M in terms of B and n: B = 3Mn 2

Molodets [167]

We are given the expression B=3Mn/2 and told to express M in terms of B and n. This means that we should apply mathematical operations on both sides of the equation so we "isolate " M on one side of the equality sign. We begin with the given equation

$B=\frac{3\cdot M\cdot n}{2}$

First, we multiply both sides by 2, so we get

$2\cdot B=3\cdot M\cdot n$

Next, we divide by 3 on both sides, so we get

$\frac{2\cdot B}{3}=M\cdot n$

Finally, we divide both sides by n, so we get

$\frac{2\cdot B}{3\cdot n}=M$

In this case, we have succesfully expressed M in terms of B and n

The volume of a cube is 1000mm3. What is the length of its side?

Damm [24]

A cube's volume is length * hight * width

since it is a cube, length hight width are all the same.

so we can use variable x to represent it.

x*x*x

which is
${ x}^{3}$

so

${x}^{3} = 1000$
cube root both sides

$x = \sqrt[3]{1000} = 10$

length of its side is 10
